In our works, we use the Tensorflow 1.13.1 [1]} for implementing our algorithms. We deploy the UAV at \((0, 0, 200)\) , the RIS at \((200, 0, 50)\)  and assume \(d/\lambda = 1/2\)  for convenience. All other parameters are provided in Table REF . In order to compare our proposed model with other baseline schemes, in this paper, we consider the techniques as follows:
